Built for Greatness: Marcelo Mantecon on Pressure, Records, and Chasing National Titles in High School

Marcelo Mantecon is Florida’s all-time 5,000m high school record holder, a Nike Indoor National Champion, and an NXN finalist. And he’s only a junior in high school.Marcelo joins the show after a soaring spring and fall season for Belen Jesuit Preparatory School in Miami, Florida, that saw him cap it off with a 4th overall finish at the Nike Cross Nationals (NXN) on December 6, 2025, with a time of 15:05.In September, he etched his name into the Florida High School Boys XC record book, running a 14:35.25 at the Southern Showcase in Huntsville, Alabama, becoming the fastest boy to do so at the distance in the state. He then took that even lower in October by running a 14:33 in the New World Fall Spectacular.  As a sophomore last year, he was named Florida’s Gatorade 2024-25 Boys Cross Country Player of the Year. He won the 5000m National Title Indoors in March of 2025 as well. His PRs include 4:15.83 for the mile, 8:16.86 for the 3000m indoor, 8:49.78 for the 2 mile outdoor, 14:14.38 in the 5000m indoors, and 14:33 in the 5000m for XC.Records show you how fast he is. We’re here to dissect how he thinks; the discipline behind the breakthroughs, the pressure of carrying expectations, and what it takes to chase national greatness while still being a high school junior.Tap into the Marcelo Mantecon Special.If you enjoy the podcast, please consider following us on Spotify and Apple Podcasts and giving us a five-star review! I would also appreciate it if you share it with your friend who you think will benefit from it. Comment the word “PODCAST” below and I’ll DM you a link to listen. If this episode blesses you, please share it with a friend!S H O W  N O T E S-The Run Down By The Running Effect (our new newsletter!): https://tinyurl.com/mr36s9rs-Our Website: https://therunningeffect.run -THE PODCAST ON YOUTUBE: https://www.youtube.com/channel/UClLcLIDAqmJBTHeyWJx_wFQ-My Instagram: ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.instagram.com/therunningeffect/?hl=en⁠⁠⁠⁠⁠⁠-Take our podcast survey: https://tinyurl.com/3ua62ffz
